EDMOND 'E USTA C H'E RENE 'G-AUDA'RT, OF PARIS, FRANCE.

.AZEPARATUS FOR HUSKING EARTHN'UTS AND THE LIKE.

Application filed October 22, 1918.

To all whom it may concern:

Be it known that I, EDMOND EUSTAGHE RENE GAUDART, citizen of the Republic of France, residing at 12 Avenue Trudaine, Paris, Seine, in the Republic of France, have invented new and useful Improvements in Apparatus for Husking Earthnuts and the like, of which the following is a specification.

This invention has for its object to provide an improved apparatus more particularly adapted for 'husking earth-nuts. The improved apparatus consists substantially of a fixed drum with a vertical axis and having .the shape of a truncated ellipsoid. This drum is traversed axially by a shaft that carries on one portion of it a screw having an ellipsoidal coregsituated inside the drum, and on another portion of it a plate or disk situated a short distancebelow the lower edge of the drum.

The drum is composed of a number of parts assembled along equatorial or meridian planes with intermediate spaces the width of which can be adjusted at will by interposing spacing pieces of suitable thicknesses.

When the screw is set in motion, the earth-nuts are charged in small quantities into an upper hopper. These nut-s pass slowly through the drum, and during their descent are continually thrown against its walls, and the repeated shocks to which the nuts are subjected efi'ect the husking of the nuts. The husks Which are projected outward pass through the intermediate spaces provided between the parts of the drum. and the kernels drop upon the lower revolving plate or disk whence they are led into a collecting hopper. The light particles and the dust collect around the screw and are discharged at the top by passing through the interior of the core if the latter is hollow and perforated.

The improved apparatus is also suitable for depulping or crushing certain fruits or nuts.

In the particular case of crushing. the screw may be adapted to be raised or lowered in such a manner as to reduce the free space between it and the drum within a certain zone.

The manner in which this invention is to be performed will now be more'particularly Specification of Letters'Patent.

described with reference to the accompanying drawings, which illustrate by way of example a constructional form of the improved apparatus. In these drawings:

Figure 1 is a vertical section of the improved apparatus on the line 11 of Fig. 2 and Fig. 2 is a side elevation thereto.

In the constructional form shown, the improved apparatus comprises essentially a fixed drum a having a vertical axis, and shaped approximately in the form of a truncated ellipsoid. The drum is composed of a number of assembled annular parts that are superposed and connected together by means of lugs 32 with interposed packing pieces 0 which by their thickness serve to adjust the width of the emptyintermediate spaces d.

The drum a is traversed axially by a shaft 6 which may be driven in any suitable manner at a speed of about 200 to 300 revolutions per minute. This shaft carries a screw f having an ellipsoidal core thatmay be solid as shown at g, or may consist of a casing of perforated sheet metal or of metal lattice-work. lower edge of the drum a, the shaft 6 has keyed onit a plate it having inclined edges. A lever i that can be fixed in any desired position, allows of adjusting the shaft 6 and consequently the screw 7 and the plate It relatively to the drum a.

WVhen the screw 7'' has attained its normal speed the earth-nuts are charged in small quantities into the hopper These nuts are carried around by the rotating screw f and are projected by centrifugal force against the sides of the drum. The nuts are gradually broken and freed from their husks which is projected through the inter mediate spaces d. The kernels drop on to the plate It and are collected in a hopper. The dust and light particles collect around the screw, and may be discharged at the top by the current of air caused by the rotation of the screw, or through the interior of the core 9 when the latter is hollow and perforated as hereinabove stated.

It is to be noted that any nuts that reach the lower end of the drum without being husked, are unable to pass out through the space left between the lower edge of the drum and the plate k, so that the said un- At a short distance from the 1.
